so we have to go out and take pictures.

We are not encouraging you to go out and take pictures as sources can't be used. You may also do some kind of home photography or use old pic's too or go out and click photos. As covid situation going on its up to you.

The highlight part is,

The photo you use must be your own.

Thank you for the response and good to see you. Wish you best of luck for the contest.
